OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 632,129, dated August29, 1899.

Application filed March 9, 1898. Serial No. 673,197. (No model.)

To all whom t may concern:

Be it known that I, JAMES J. LANAHAN, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Oil-Cups, of which thefollowing is a specification.

My invention relates to an improved oileup chiefly adapted for use uponthe rollingstock of railways; and the object is to, provide a cup fromwhich the cover or cap can be easily and quickly removed and replaced,but cannot be shaken or jarred involuntarily therefrom. The usualdevices now in use either employ a cap which fits snugly over the mouthof the cup or which screws over Said mouth.

Withthe first above-mentioned device the mere dropping of the cap uponthe ground is extremely liable to dent it sufficiently to prevent itsfitting over the mouth of the cup, and a cap of this nature is easilyshaken loose and lost. The screw-threaded cap is more expensive tomanufacture, the thread is easily distorted by the rough usage incidentto every railway, and even though it be screwed very tightly in placethe continual jarring and rattling must in time cause it to work looseand drop from the cup. Vith my improved device these disadvantages areall eliminated, as the dropping of the cover would not be likely toinjure or dent the spring portions, and the coveris always held withinthe mouth of the cup with a spring force, thus preventing the jar orrattle from shaking it loose.

My invention will be fully and clearly hereinafter described andclaimed, reference being had to the accompanying drawings, in whichfFigure 1 represents a side elevation of my improved oil-cup, showing thecap in place thereon. Fig. 2 represents a vertical central sectionthrough an oil-cup and cap, showing the invention and aslightly-modified form of oil-cup. Fig. 3 represents a det-ached sideelevation of the cap. Fig. .Lrepresents a top plan view of the oil-cupshown in Fig. l.

Referring to the drawings in detail, l represents the body of theoil-cup, which may be made in any suitable form or shape. It is providedwith the usual opening 2 for the oil to pass through and may have theusual means for limiting the ilow ofoil, if desired.

The top of the rim of the oil-cup is provided with an interiorinward-extending rib 3. (Shown in Fig. 3.)

The top 4 of the cover or cap is provided with a milled or roughenededge to facilitate its handling, and a series of spring members 5 extendsubstantially vertically downward from a circle upon the under surfaceof said top. These members 5 are all provided with a shallow exteriordepression or groove 6, terminating at the lower end in the rib 7,substantially as shown in Fig. 3, and when the cap is forced or sprunginto the mouth of the cup the rib 3 on the interior of the cup end gagesin the exterior depression 6in the members, and the ribbed lower ends 7of said members fitting against the incline at the termination of therib 3 hold the cap or cover within the mouth of the cup with a springforce and prevent its involuntary displacement therefrom by jarring, asis usual with the loosely-htted or screwed-over cap.

It might prove advisable in manufacturing to t the cover or cap overinstead of into the mouth of the cup, or provide the cup with a springportion instead of the cover or cap.

I claim as my invention- The combination with an oil-cup provided withan interior inwardly-extending rib, of a cover or cap having a series ofspring mem bers adapted to fit in the mouth of said cup and havingexterior depressions iitting over the rib of the cup, substantially asdescribed.
